IMPROVEMENT IN CLIP KING-'BOLTS AND PLATES.

Specification forming part of Letters Patent No. 139,855, dated J une17, 1873 5 application filed March 8, 1873.

To aLl Iwhom it may concern:

Be it known that I, HENRY M. BEECEEE, of Plantsville, in the county ofHartford and State of Connecticut, have invented certain new and usefulImprovements in Clip King- Bolts and Plates, of which the following is aspecification In my improved clip king-bolt and plate there is a recessin the center` of the bearin g-surface between the arms of the bolt, andthe sheet-metal concave-plate which cap the axle has a projection whichrests in said recess, when the two are placed together, and prevents theplate from working endwise with the axle and out from under thekingbolt, as hereafter described.

In the accompanying drawing, Figure 1 is a central vertical section of aclip king-bolt and plate, which embody my invention, the same beingtaken on a line transversely to the axle on which they rest. Fig. 2 is aplan or top view of said plate when removed from the king-bolt, and Fig.3, is a central long- 'Ihe king-bolt A is of the class generally knownas clip kingbolts, from the fact that it` embraces the axle instead ot'running through it. Such kingbolts are old, and may be made in any ofthe ordinary forms. My bolt differs from the old ones by being providedwith the recess a between its arms, and directly opposite and under thecenter of the stem b of the bolt A. B designates a plate, which I preferto form of sheet-metal, and it is of concave form and very similar to anordinary telly-plate. In'

the middle of this plate I swage aprojection, c, projecting from theconvex` side of the plate, and of a form corresponding to that of therecess a in the boltA; in fact, the f 'orm of the whole plate is such asto tt between the arms of the bolt, as shown in Fig. 1, while the plateB is longer than the clip part of the bolt is wide; the broken lines inFig. 3 representin g the width of the bolt. The axle C D of a carriageis generally made of wood and iron. In the drawing, C designates thewood portion and D the iron. I place the plate B upon the axle C D, andthen place the bolt A thereon, with the projection c resting in themanner. The projection and recess prevent the plate from movinglongitudinally out from under the bolt, and thus the plate forms a seatfor the bolt and prevents it from wearing into the wood C, while thebearing-surface of the bolt is not enlarged, but remains, like that ofthe ordinary king-bolt, just the width of the clip-arms, as indicated bybroken lines in Fig. 3.

Thus it will be seen that the plate `does not brace the bolt laterally,nor add to its rigidity. In case the plate B, of the length shown, wasrigidly secured to the bolt A, it would brace the bolt ,so firmly thatwhen sudden lateral motion is given to the carriagebody the concussionwould be liable to break the king-bolt, as vhas been found to be thecase with king-bolts thus braced; but with a king-bolt having a narrowbearing-surface at the fork, the bolt will give more or less, at itsjunction with the plate, and thereby the concussion is less severe andthe bolt less liable to be broken.

It is ofcourse evident that a recess may be formed in the plate B and acorresponding projection formed on the bolt, instead of forming theprojection on the plate and the recess in the bolt; or both may beemployed, as shown in the drawing 5 and the end of the small projectionor rivet formed on the bolt `may be headed, if desired, to hold theplate and bolt together temporarily, until secured in their nal positionupon the axle.

I claim as my invention- 1. The concave metal king -bolt clip B,provided with the projection c,or its equivalent, to prevent the clipfrom working longitudinally out `of place, substantially as shown anddescribed. l

2. The combination of the plate B, having the projection c, with theking-bolt A, having the recess a', substantially as and for the purposedescribed.
